“A few months ago, Casares was offered a seventeenth-century original edition of Don Quixote for one million euros. He recognized it as a well-known forgery from the nineteenth century, worth no more than €200,000.”

Ha, I was thinking when I was reading that piece that Borges could almost have written the scenario himself. The biggest irony is that (if I remember correctly) it’s the very book about which Borges later said he wanted to personally apologise to all the purchasers. At least if it was The Book of Sand there’d only be the one volume.
